Ocular neuromyotonia after radiation therapy
American Journal of Ophthalmology
|December 15, 1986
Summary
Radiation therapy for tumors near the sella turcica can cause ocular neuromyotonia, a rare eye muscle spasm. This cranial neuropathy, characterized by abnormal eye movements, appears to be most commonly caused by prior radiation exposure.
Area of Science:
- Ophthalmology
- Neurology
- Oncology
Background:
- Ocular neuromyotonia is a rare condition causing intermittent, single-eye movement abnormalities.
- It stems from abnormal electrical activity in cranial nerves controlling eye muscles (third, fourth, or sixth).
- Previous treatments for tumors in the sella turcica and cavernous sinus regions are implicated.
